The Active Ingredient Is: Diamine Oxidase (DAO) Enzyme

Diamine oxidase, or DAO, is an enzyme that drives the oxidative deamination of histamine in the digestive tract. This form is supplied as DAO from porcine kidney extract, standardised to a defined enzyme activity for consistency.

The DAO activity in this product is provided via DAOgest porcine kidney extract, with stability characteristics designed to maintain enzyme function in the digestive system. This approach concentrates on local activity in the gut instead of systemic distribution. This formula also includes microcrystalline cellulose, a vegetarian capsule, and ascorbyl palmitate to support product integrity.

What Does Diamine Oxidase Do?

Diamine oxidase helps break down histamine in the digestive tract, contributing to normal digestion in the gut. EFSA and NHS guidance emphasise the usual roles enzymes play in digestion, with activity kept in the digestive system rather than systemic sites.

In this formulation, the enzyme acts locally in the gut to support histamine breakdown as histamine-containing foods are eaten, helping to keep normal digestive responses in the digestive tract. This supports the intended digestive health framework without systemic effects.
